Starrett Outside Micrometer

This item is an outside micrometer, manufactured by Starrett, a well-known brand for precision measuring tools. It features a C-shaped frame, likely made of cast iron or steel, finished in a dark, possibly black or dark grey, enamel or baked-on coating. The frame exhibits some areas of paint loss and chipping, particularly near the thimble and anvil, suggesting regular use and age. The thimble and sleeve are made of a lighter, shiny metallic material, possibly chrome-plated steel, and have clearly visible etched or engraved measurement markings. The thimble features a knurled grip for ease of rotation. The anvil and spindle tips appear to be flat and made of hardened steel, essential for accurate measurements. The micrometer shows signs of wear consistent with tools of its type and age, including surface abrasions and some discoloration on the metallic parts. The presence of the 'STARRETT' brand name clearly visible on the frame indicates its maker and suggests a high level of craftsmanship and accuracy. This particular model appears to be an older, traditional mechanical micrometer, likely from the mid-20th century, given its aesthetic and visible wear patterns. Its sturdy construction and precision engineering are hallmarks of Starrett products, designed for durability and reliable performance in industrial or workshop settings. The overall condition suggests it has been a working tool, and its functionality would need to be verified for a complete appraisal.
